Bacidina delicata

Local name: mjölig lundlav

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Bacidina delicata faces severe pressure from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its bark substrates. Urban expansion and forest management practices that favor younger tree stands reduce the availability of mature deciduous trees with suitable bark chemistry. Climate change compounds these threats by altering precipitation patterns and increasing temperature stress on both the lichen and its host trees.

Threat summary

Habitat

This crustose lichen grows exclusively on the smooth bark of mature deciduous trees, particularly favoring nutrient-rich bark with specific pH conditions. It is typically found in old-growth and semi-natural forests, parks, and tree-lined areas with low air pollution levels.
